Outliner: Add buttons to set active camera

Add buttons to the left column to set the active camera. The active
camera currently shows a check, and other cameras draw a dot.

For some reason the dot doesn't have a proper hitbox area.

Right now the function to set the camera is done from button callbacks,
but this could also easily be done from outliner_select.c.

Outliner: Draw left column for activation/mode toggle

In Scenes view mode, a column is added when the toggle is enabled. In
view layer mode, the scene collection has a space next to it where a
expand/collapse triangle could be drawn, so this also offsets the tree a
unit to the left when in view layer display mode.

fix spelling

Outliner: Add property to show the left column

Add a property to show the left column for the activate/mode toggle
buttons. This needs versioning to apply to the default scene.

Remove unnecessary `uiButSearchData` struct

This doesn't add anything useful if we already have a struct for search
buttons. At the very least it should not be allocated.

Also uses clearer names for `uiButSearch` members.
